Not all types of hearing loss are the same. How that loss is caused may make a difference to the hearing solutions that will be recommended to you.
Here we take a look at four types of hearing loss starting at conditions that affect the outer ear, the inner ear, and finally the brain.
There are a number of reasons for that. Some of them can be temporary in nature such as a wax blockage, a middle ear infection or fluid in the middle ear as a result of colds or allergies.
Other causes might be more permanent such as a hole in the ear drum or by a condition called otosclerosis where a bony growth forms around a small bone in the middle ear, preventing it from vibrating when stimulated by sound. This condition is sometimes known as Surfers Ear.

Surgery to correct the problem might work, but in other cases hearing aids are prescribed to get clear sound past the damaged part of the ear to the inner ear where it sends the signal to your brain.
There can be a number of reasons for that:
Before we explore this further, we need to look at Sudden Sensorineural Hearing Loss.
Sudden Sensorineural Hearing Loss - if you experience sudden hearing loss in one ear, then make an appointment to see your doctor immediately. There are a number of serious causes for this which you want the doctor to address. Depending on the cause, quick assessment and treatment can help your hearing recover.
Causes of Sudden Sensorineural Hearing Loss appears to be associated with viruses or bacterial infections. Certain medications can also affect your hearing, so it is important that you regularly consult with your doctor about medication prescribed to you.

Most common Sensorineural Hearing Loss happens gradually over time and accounts for about 90% of all hearing loss.
In this type of hearing loss, hairs in the cochlea - the semi-circular structure in your inner ear - have died off. Usually it is the hairs responsible for transmitting higher frequencies which go first. And they just happen to be the frequencies we need to correctly discern the nuances of speech.
Because of its gradual nature, it is estimated many people don’t recognise their hearing loss until up to half of those hair cells have gone.
While this process cannot be reversed, it can be successfully helped most of the time with the use of hearing aids.
Since age is a factor in hearing loss (it comes with its own specific name: presbycusis), it is important to add a regular hearing check to your health routine after the age of 50.

It is not a common condition and its causes may vary:
Scientists are still researching the causes and risk factors for the condition. Auditory Neuropathy has a genetic link and it is also a risk factor for those born prematurely or were a low birth weight
As the name suggests, it is possible that your hearing loss is a combination of both conductive hearing loss and sensorineural hearing loss.
This is why it is so important to have regular hearing tests and work with both your GP and your audiologist to look at ways to help maximise your best possible hearing.
